प्रश्न
If a cyclist doubles his speed while negotiating a curve, how does the tendency to overturn vary?
पर्याय
Remains unchanged.
Doubled.
Halved.
Quadrupled
MCQ
उत्तर
Quadrupled.
Explanation:
The tendency to overturn depends upon centrifugal force, `"mv"^2/"r"` experienced by the cyclist (in this frame of reference)
Ifv is doubled then v2 = 4v2
`"mv"^2/"r" = 4 "mv"^2/"r"`
∴ Tendency to overturn is quacbupled.
